can we get rid of the call to self.store.process_replication_rows above, given that is also called by on_rdata ?
There was a problem hiding this comment.
Done. I've moved the self.notifier.notify_replication() after the on_rdata(..) call in case anything listening was requiring the store to have processed the replication.

this means that all this stuff is going to happen on the master, where it previously did not (iirc each replication client receives its own replication data back). Is that not going to be a problem for any of these?

iirc each replication client receives its own replication data back
We filter out the echoes before we get here, as RDATA includes the sending instance name, so that shouldn't be a problem. Really, I think its a bug that this hasn't been happening on master, e.g. if we split out receipts etc but keep /sync on master then /sync requests won't get told about new receipts.

I went looking for that code, but couldn't find it. Can you point me to it?

at some point in this project (not necessarily during this particular PR), could you add some docstrings to WorkerPresenceHandler and PresenceHandler to explain how they differ?

nods And type hints.

I'm a bit confused about why these are being added. They don't seem to be called or defined anywhere in this diff?
There was a problem hiding this comment.
Err, sorry. A commit in a different PR needed them to be defined on both to appease mypy, I'll back that out.
There was a problem hiding this comment.
Oh actually, they are needed now. This is because hs.get_presence_handler() returns BasePresenceHandler now instead of PresenceHandler. So either we a) add a no-op impl here, or b) assert the type in the calling code. I vaguely prefer the former to the latter.
FTR without these stub impls:

I'm assuming that this is a complete lift-and-shift of GenericWorkerPresence. Is there anything else I should know?

Nope, this is just a straight copy and paste.

Synapse 1.33.0rc1 (2021-04-28) ============================== Features -------- - Update experimental support for [MSC3083](matrix-org/matrix-spec-proposals#3083): restricting room access via group membership. ([\#9800](#9800), [\#9814](#9814)) - Add experimental support for handling presence on a worker. ([\#9819](#9819), [\#9820](#9820), [\#9828](#9828), [\#9850](#9850)) - Return a new template when an user attempts to renew their account multiple times with the same token, stating that their account is set to expire. This replaces the invalid token template that would previously be shown in this case. This change concerns the optional account validity feature. ([\#9832](#9832)) Bugfixes -------- - Fixes the OIDC SSO flow when using a `public_baseurl` value including a non-root URL path. ([\#9726](#9726)) - Fix thumbnail generation for some sites with non-standard content types. Contributed by @rkfg. ([\#9788](#9788)) - Add some sanity checks to identity server passed to 3PID bind/unbind endpoints. ([\#9802](#9802)) - Limit the size of HTTP responses read over federation. ([\#9833](#9833)) - Fix a bug which could cause Synapse to get stuck in a loop of resyncing device lists. ([\#9867](#9867)) - Fix a long-standing bug where errors from federation did not propagate to the client. ([\#9868](#9868)) Improved Documentation ---------------------- - Add a note to the docker docs mentioning that we mirror upstream's supported Docker platforms. ([\#9801](#9801)) Internal Changes ---------------- - Add a dockerfile for running Synapse in worker-mode under Complement. ([\#9162](#9162)) - Apply `pyupgrade` across the codebase. ([\#9786](#9786)) - Move some replication processing out of `generic_worker`. ([\#9796](#9796)) - Replace `HomeServer.get_config()` with inline references. ([\#9815](#9815)) - Rename some handlers and config modules to not duplicate the top-level module. ([\#9816](#9816)) - Fix a long-standing bug which caused `max_upload_size` to not be correctly enforced. ([\#9817](#9817)) - Reduce CPU usage of the user directory by reusing existing calculated room membership. ([\#9821](#9821)) - Small speed up for joining large remote rooms. ([\#9825](#9825)) - Introduce flake8-bugbear to the test suite and fix some of its lint violations. ([\#9838](#9838)) - Only store the raw data in the in-memory caches, rather than objects that include references to e.g. the data stores. ([\#9845](#9845)) - Limit length of accepted email addresses. ([\#9855](#9855)) - Remove redundant `synapse.types.Collection` type definition. ([\#9856](#9856)) - Handle recently added rate limits correctly when using `--no-rate-limit` with the demo scripts. ([\#9858](#9858)) - Disable invite rate-limiting by default when running the unit tests. ([\#9871](#9871)) - Pass a reactor into `SynapseSite` to make testing easier. ([\#9874](#9874)) - Make `DomainSpecificString` an `attrs` class. ([\#9875](#9875)) - Add type hints to `synapse.api.auth` and `synapse.api.auth_blocking` modules. ([\#9876](#9876)) - Remove redundant `_PushHTTPChannel` test class. ([\#9878](#9878)) - Remove backwards-compatibility code for Python versions < 3.6. ([\#9879](#9879)) - Small performance improvement around handling new local presence updates. ([\#9887](#9887))
